Application filed January 4, 1915. Serial No. 503.

To all whom it may cancer):

Be it known that I, JoHN Hours, a citizen' of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Dish-Washing Machines, of which the following is a full and complete specification.

My invention relates to that class of devices 'used for washing dishes, or the like, and provides means whereby said dishes may be cleansed from particles of food 'or other undesirable matter. I

The object of my invention is to provide a mechanism which will scrub and wash every portion of a plate or dish placed within said mechanism and thoroughly cleanse said platesor dishes in a continuous operation and deliver same upon a drying table. I at-' tain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 shows a plan view of a dishwashing machine comprising my invention. Fig. 2 shows a side elevation thereof. Fig. 3 shows an enlar ed plan view of that partof the mechanism which performs the dish scrubbing operation. Fig. 4 illustrates a vertical sectional view through the juxtaposed brushes and plate guiding chute thereover.

Referring to Figs. 1 and 2, the invention comprises a tank composed of the side walls 1 and 2, the ends walls 3 and 4, the bottom 5 and the dividing wall 6 forming the washing compartment 7 and the rinsing compartment 8.

Suitably located within the washing compartment 7 are the dish scrubbing brushes 9 and '10, the ends of the bristles 11 thereon extending toward each other at a point approximately midway between said brushes 9 and 10.

The brush 10 is secured to the flange 12 of the shaft 13 which is mounted in the bearing 14, supported on the end wall 4. Extending through the side wall 2, and attached to the end of said shaft 13 is a pulley J 15 which is rotated by the belt 16 driven by the-pulley 17 on the line shaft 18. A pulley 19, also secured to the line shaft 18, drives the crossed belt 2Q, which rotates the pulley 21 in opposite direction to. the rotatlon of the pulley 15, said pulley 21 being attached to the shaft 22, extending through the side wall 1 and through the bearing 23 secured to the end wall 4, and is provided near its in- Speci flcation of Letters Patent.

ner end with a flange 24 to which is secured the brush 9, which is thereby rotated in opposite direction to that of the brush 10,

causing the-bristles 11 on said brushes to sweep all portions of the plate 25 which is dropped between them through an open ended dish chute 26 mounted by the bracket 27 on' the bearing 14 and by the bracket 28 on the bearing 23. The said chute 26 is positioned over the vertically disposed brushes and is concaved at its discharge mouth to fit about the circular brushes, whereby dishes passing between said brushesare guided and held during a scrubbing operation. Attentio ris. also called to the fact that the-dish receiving chute 26 has its mouth extended above the surface of thev scrubbing fluid,

whereby the fiat dishes may be readily inserted therein and be guided through the immersed discharge end ofthe chute and juxtaposed brushes. The plate 25 then drops from between the bristles 11 of the brnshes'9 andlO through the water 29, which is supplied to the washing compartment 7 by the pipe 30 equipped with a regulating valve 31, upon a guide 32 which is secured to the underside of the brackets 14 and 23, and slides therefrom upon an endless belt 33, which is carr1ed near the bottom of the tank over a roller 34 suitably mounted within said compartment 7. Said endless belt 33 is carried at its hlgher elevation, upon the driving roller 35 suitably mounted at the top of the compartment7, whose end extends through the side wall 2 and has secured thereto the pulley 36, which is rotated by the belt 37 driven by the pulley 38 attached to the shaft 13. The plates 25 are thus-carried by the endless belt 33 out of the water in the compartment 7 over the dividing wall 6 to which is attached, within the rinsing compartment 8, a

downwardly extending chute. 39, upon which the plates 25 slide past the bristles 40 of the revolving brush 41 mounted on a shaft 42, carriedsuitably by the side wall 2 and extending through the side wall 1, hav-' ing attached to the end thereof a pulley 43,

which is rotated by a belt 44 driven by a pulley 45 attached to the end f a roller shaft 46 which extends'through the side walls 1 and 2, and has secured to the other end thereof a pulley 47, which is rotated by the belt 48, driven by'the pulley 49 on the driving roller 35.

An endless belt 50, which is mounted on the roller shaft 46, located near the bottom ofthe rinsing compartment 8, and the roller 51 located at the top of said rinsing compartment/S and over the end wall 3, carries the plates 25 falling on said belt 50, from the chute 39 to the top of the rinsing compartment and onto a downwardly inclined delivery chute 52 which extends to a drying table 53, from which said dishes may be removed and disposed of as desired.

An overflow funnel 54 is provided within the washing compartment, which maintains an even level of'the water 29, and carries the surplus thereof through the pipe 55 connecting with the drainage pipe 56, attached to the bottom of the washing compartment 7, and provided with a valve 57, to a sewer pipe 58 of'any'desired length and disposition.- A similar overflow. funnel 59 located suitably in the rinsing compartment 8 provides means for draining the surplus of the water 60, admitted into said rinsing compartment 8 by the water supply valve 61, through the attached drain pipe 62 con-- necting with the drain pipe 63 which is provided with a valve 64 and connects with a sewer pipe 65.

In use, the washing compartment 7 is filled with hot water and suitable compounds after which the scrubbing machineery is set into operation. Dishes dropped through the dish guard 26 and between the bristles 11 on the oppositely revolving brushes 9 and 10 are quickly freed from all particles of food and waste material and drop upon the endless belt 33 which carries said dishes into the rinsing compartment 8, where they receive a further cleansing operation by means of the revolving brush 41, after which they pass upon the endless belt 50 which carries said dishes onto the delivery chute 52 and thence upon the drying table 53.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is I-- 1. In a washing-machine having a washing compartment and a rinsing compartment, each being provided with means for admitting a washing fluid and a rinsing fluid thereto, means for maintaining a constant level of said fluids, and means for draining} the same from the compartments; the com ination of two oppositely revoluble scrubbing brushes, whose bristles are adapted to cleanse dishes dropped between them, a vertically disposed dish chute mounted above said brushes,a guide mounted below the aforesaid brushes, an inclined endless belt positioned in the washing compartment for delivering washed dishes from the guide to the rinsing compartment, a downwardly inclined chute positioned in the rinsing compartment, adapted to-receive dishes discharged from the washing compartment, an upwardly inclined endless belt mounted in said rinsing compartment for discharging the dishes from the aforesaid rinsing compartment, and a revoluble cleansing brush positioned over the downwardly inclined chute the same being adapted to contact with dishes traveling upon said chute.

2. A dish washing apparatus comprising a pair of axially alined vertically disposed circular brushes having their bristled scrub bing faces in close relation, means for imparting rotation to the brushes in opposite directions, an open ended vertically disposed dish guiding chute afixed over the brushes, the discharge mouth of which chute is curved to conform to the contour of the circular brushes about which said discharge mouth fits, and a receiving conveyer positioned under the brushes.

3. In a dish washing machine having a compartment, means for admitting fluid thereto, and means for maintaining a constant level of said fluid therein; the combination of a pair of oppositely revolublc scrubbing brushes positioned in the compartment to be constantly submerged, and an open ended vertically disposed dish guiding chute afiixed over the brushes, the chute being provided with a delivery mouth that projects above the surface of the fluid, and a discharge mouth that is concaved to conform to the contour of the brushes about which it is fitted, and a receiving conveyer positioned under the brushes.

In testimony whereof I hereunto aflix my signature in the presence of two subscribing witnesses.
